  • Patent number: 4079077
    Abstract: The crate comprises an apertured bottom portion and inclined interconnected arms forming a succession of V-shaped structures connecting the outside of the bottom portion to a quadrangular upper girdle disposed outside the arms. The arms are in vertical planes and define at their interconnections horizontal top stops and bottom stops. Opposite sides of the crate have respectively upper reference members and lower reference members. The upper reference member overlaps the lower reference member of an adjacent crate when the adjacent crate has the same orientation as the first-mentioned crate and is correctly positioned relative to the latter to ensure that the pitch of the V-shaped structures is maintained across the joint between the crates.
